Question

A solid ice of 11 x 8 x2 inches is made into rod of dia 4 inch. What is the lenge of rod?

Answer 1

Answer:

Step-by-step explanation:

Volume of ice block (cuboid) = l * b * h

                                               = 11 * 8 * 2  

                                               = 176 inches

r -> radius , h -> height/length  

Volume of rod (cylinder) =  π * r^2 * h

                                         = 22/7 * 4^2 * h

                                         = 352 * h /7

Volume of rod = Volume of ice block

=> 352 * h /7 = 176

=>  h = 176 * 7 / 352

=>  h = 3.5 inches
